Over the
years, Luxman's strength in engineering excellence has always been most evident
in amplifier design.
The M-05
(and M-02) represent the latest in electronic technology from Luxman.
These power
amplifiers contain the most current circuit designs, including Duo-Beta with
single-stage amplification and L.E.D. bias circuitry.
And as the
models from which allLuxman amplifier sections are designed, the M-05 and M-02
utilize discrete output transistors and maintain high dynamic power even into
low impedance loads.
The
top-of-the-line M-05 is a pure class "A" configuration and sonically
ranks with the finest amplifiers in the world.

Power Supply and "Single-Stage" Amp is
now reinforced by "LED" Bias Current
The 1st
stage we ventured to use high Gm, low-noise FET for head-amp at the 1st stage.
In this way, we succeeded in removal of the 2nd stage to form an ideal amp
having only one stage for voltage amplification.
Ample Power
Supply
A slim but
effective power transformer with outstanding regulation is newly designed for
this high quality separates, which ensure longlasting, stabilized performance
in combination with the select capacitors specially developed for audio use.
Especially, the power transformer employed this time offers far better
efficiency than those with the conventional EI core, which makes it possible to
reproduce soild bass sound
Unconditional
Stability
"Single-Stage"
amp thus created totally banishes various hums inclusive of power supply noises
hitherto amplifies by the 2nd stage, and at the same time ensures high
stability with the highest slew rate.
LED Bias
Current System
Unprecedented
speedy attack and decay are given in the actual auditory feelings thanks to our
unique bias current circuit employing LED's in lieu of normal diodes. In fact,
the LED provides very sharp rise and decay in the statics when compared with
silicon diode, and therefore ensures stable bias power supply. In addition, it
is possible to cope with even an unexpected, sudden fluctuation due to its
inherent high-speed response.
Furthermore,
the inter-terminal voltage per LED is higher than that of diode in general, and
to share the same voltage the smaller number of LED's will do in comparison
with that of diode. Thus, the esponse speed as well as the decay and rise
characteristics show multiple effect, providing conspicuous improvement in the
auditory feelings. Unexperienced pure sound is now unveiled.
